Absolutely. All you need to do is compare survival rates.
The Germans usually treated Allied prisoners more or less properly.
Russian, Polish and other subhuman POWs were a different story entirely.
One wonders on this: the attitude towards the Slavs was little better than that to Jews, etc. But the Germans actually considered themselves relatives of the Brits/French/US, could this be a leftover from when Kaiser Bill was King George's cousin?
I guess being a slav in a German camp would be about on par with being a allied guest of the emporer. Maybe worse.
Conditions at Luftwaffe camps, especially for Allied air crews, was light years better than those at camps run by the SS.
Worst of all for Soviet POWs was that for the few that survived the war, their reward was to be sent to Siberia, if not killed, by Stalin, who considered Soviet POWs as traitors.
Will the families of the million German soldiers who died in Soviet death camps get compensation?
